| banding patterns of the chromosomes of cebus albifrons. comparative study with cebur apella. | quinacrine- and giemsa-banding studies of the chromosomes of cebus albifrons permitted to obtain a pattern that characterizes the species. the topography of the bands has been compared with that of cebus apella. each chromosome pair of c. albifrons has a homologue in c. apella. the differences between the two karyotypes are the result of five pericentric inversions. | 1976 | 819340 |
| experimental biharzial bladder cancer: tryptophan metabolism in nonhuman primates experimentally infected with schistosoma haematobium. | a nonhuman primate species infected with schistosoma haematobium provided a model system for controlled studies on biharzial bladder cancer. urinary excretion of tryptophan metabolites by capuchin monkeys (cebus apella) was similar to that of humans when expressed per g creatinine. liver tryptophan oxygenase activity of the capuchin monkeys was comparable to that of humans. excretion of 3-hydroxykynurenine and 3-hydroxyanthranilic acid was elevated above control levels in capuchin monkeys infect ... | 1976 | 815556 |
| early changes in protein synthesis following spinal cord hemisection in the cebus monkey (cebus apella). | the short term effects of spinal cord hemisection on protein synthesis in the cebus monkey were studied by measuring the uptake of [3h]lysine into the trichloroacetic acid (tca) precipitable and non-precipitable fractions of spinal cord. animals were sacrificed 3, 6, or 13 days after hemisection. two normal animals and a 3 day sham operate were utilized as controls. all data were pooled and subjected to analysis of variance. significant group differences were resolved by a standad t-test over po ... | 1976 | 821580 |
| isolation and characterization of two new herpes-like viruses from capuchin monkeys. | two herpes-like viruses were isolated from capuchin monkey (cebus apella) brain and (cebus albifrons) spleen cell cultures, respectively. both isolates induced similar cytopathic effects consisting of rounded and ballooned cells in the original monkey cell cultures and in a wide range of permissive cell types. neutralizing antibody to each virus was present in serum from the capuchin monkey from which it was isolated, but the two viruses did not cross-react by neutralization. fluorescein isothio ... | 1976 | 823119 |
| the catecholamine pontine cellular groups locus coeruleus, a4, subcoeruleus in the primate cebus apella. | the distrubution of ca neurons of areas a6 and a4 was delineated in cebus apella monkey using the fluorescent histochemical technique of falck and hillarp. cytospectroscopy was utilized for ca differentiation. the noradrenergic cellular regions a6, a4, and subcoeruleus have extensively increased in size in the cebus as compared to the rat and appear to be separate nuclear regions. area a4 is made up of two cellular subgroups: a more abundant lateral magnocellular area with cells as large as 45 m ... | 1976 | 824016 |
| naturally occurring tuberculosis in a squirrel monkey and a cebus monkey. | tuberculosis was detected in a brazilian squirrel monkey (saimiri sciureus) and in a cebus monkey (cebus apella). both of these animals were housed in the same room with a rhesus monkey (macaca mulatta) subsequently found to be tuberculous. all 3 of the monkeys died within a 4-month period. | 1976 | 824261 |
| neurohistologic observations of the cebus apella monkeys soft palate mucosa. | a neurohistological observation was done in the solf palate mucosa of the cebus apella monkey. six mucosa were employed and were removed after perfusion of each animal, with 10% formalin solution, through the external carotid artery of the right side. the mucosa was removed together with the muscular layer and salivary glands. the histologic analysis was performed and therefore the pieces were prepared by the "de castro" technic of silver impregnation. the material was embedded in the vertical s ... | 1976 | 824693 |
| the transport of vitamin d in the serum of primates. | "transcalciferin" (the serum transport protein for cholecalciferol and related substances) of two new world monkeys, cebus apella and cebus albifrons, was found to be immunologically identical with the transcalciferin of other monkeys and partially with that of man. in contrast with the alpha-globulin mobility of the transcalciferin of other primates, the transcalciferin of cebus monkey has the electrophoretic mobility of albumin. most of the serum 25-hydroxycholecalciferol was precipitable with ... | 1976 | 827286 |

| neurohistological observations on the tongue of the tufted capuchin, cebus apella linnaeus, 1758. | neurohistological observations of the tongues of the adult monkeys cebus apella are described. it was noted that the cebus tongue presents few vallate papilae situated mainly in the posterior and lateral parts; fungi and filiforms are spread all over the dorsal surface. histologically there was evidence that numerous nerve fibres of variable size come from the deep layers of the tongue to the surface structure. in many regions they constitute plexuses, other cross the muscular and glandular laye ... | 1977 | 406648 |
| ultrasound as a new method of male contraception. | twenty male cats were treated once or twice with 1 watt/sq cm of ultrasound for 10 minutes. each of 24 male dogs received one to three treatments with 1 watt/sq cm for 10 minutes. another six dogs were treated with 2 watts/sq cm for 15 minutes. four cebus apella monkeys were treated with the same dosage as that used for the cats and dogs. a dosage of 1 watt/sq cm for 10 minutes was also applied to four human patients without the use of anesthetics, and no pain or side effects were noted. in all ... | 1977 | 407106 |
| split-line patterns of the mandible following masseterectomy in adult and growing monkeys. | architectural changes of the mandibular ramus following masseterectomy were analyzed by means of the split-line technique in both adult and growing monkeys. the right masseter muscle was resected in ten tufted capuchin monkeys (cebus apella) and they were sacrificed following a 12-month period. along with modifications in the shape of the mandible, the masseterectomy induced structural changes as revealed by alterations in the split-line patterns. these changes were much more evident in the adul ... | 1977 | 407803 |
| movement disorders induced in monkeys by chronic haloperidol treatment. | after several months of treatment, cebus apella, cebus albifrons, and saimiri sciurea monkeys maintained on haloperidol, in doses of 0.5 or 1.0 mg/kg orally 5 days per week, began to display severe movement disorders, typically 1-6 h post-drug. cebus monkeys exhibited violent, uncontrolled movements that flung the animals about the cage. such episodes usually lasted only a few minutes, recurring several times during the period following drug ingestion. writhing and bizarre postures dominated the ... | 1977 | 408858 |
| innervation of the palatine mucous membrane in the cebus apella monkey. | a histological study was conducted on the innervation of the cebus apella palatine mucosa. ten monkeys were used for the present study. after perfusion with 10% formalin, the whole hard palate mucosa was removed in one piece and made into histological sections according to de castro's method for silver impregnation. we concluded that the nerve fibers form free endings and organized corpuscles, like meissner corpuscles. free nerve endings are numerous in the hard palate mucosa and they show a gre ... | 1977 | 414375 |
| multifocal candidiasis in a capuchin monkey (cebus apella). | candidiasis involving nasal, pharyngeal, and intestinal mucosal surfaces and a pharyngeal lymph node was demonstrated microscopically in a young adult female capuchin monkey (cebus apella) experimentally infected with schistosoma haematobium (iran strain). persistent nasal exudation and weight loss characterized the clinical disease preceding the animal's death. | 1977 | 21298 |
| the reproductive cycle of the capuchin (cebus apella). | six, mature female capuchins, cebus apella, were used to study occurrence of bleeding, the length and phases of the menstrual cycle, and the gestation period. during a 3-month period the menstrual cycle was determined to be 21 days, including an average of 4 days in which bleeding was detectable. it was found that only proestrus and estrus could be reliably identified during the menstrual cycle by the use of vaginal smears. each female was housed with a male for a sufficient time to allow insemi ... | 1977 | 412999 |

| a fatal epizootic of undetermined etiology in new world monkeys. | a peracute epizootic disease, strikingly characterized by profuse terminal hemorrhaging from the lungs, caused the deaths of 104 squirrel monkeys and 3 capuchin monkeys over a 22-month period. the case fatality rate was 100%. the pulmonary hemorrhaging was often accompanied by pulmonary edema and congestion, interstitial pneumonia, and hydrothorax. additional histologic lesions included interstitial nephritis, hepatitis and hepatic necrosis, adrenalitis and adrenal necrosis, myocarditis, splenic ... | 1982 | 31991987 |
| constitutive heterochromatin polymorphism in lagothrix lagothricha cana, cebus apella, and cebus capucinus. | we describe the c-bands in the karyotypes of lagothrix lagothricha cana, cebus apella and cebus capucinus. the c-banding patterns show both a high degree of polymorphism as well as the presence of terminal and interstitial c-bands. varying amounts of heterochromatin result in dimorphism of some chromosome pairs. the high incidence of chromosome rearrangements found in the cebidae may be due to the presence of terminal and interstitial c-bands. | 1983 | 31991965 |
| application of a primate model for tardive dyskinesia. | persistent signs of oral dyskinesia (tongue protrusion and facial grimacing) had developed as a result of earlier chronic treatment with neuroleptics in a cebus apella monkey. when this animal was given single doses of any classical neuroleptic, a transient deterioration of dyskinesia occurred, preceded by a temporary abolishment of dyskinesia sometimes with an attack of acute dystonia. fluphenazine (5-25 micrograms/kg) causes dose-related deteriorations of dyskinesia. six different drugs were t ... | 1983 | 6846025 |
| [anatomomicroscopic study of the transition of the sigmoid sinus--1st portion of the internal jugular vein in the monkey cebus apella linnaeus, 1758. comparative study]. | the author verified that the transition between the sigmoid sinus and first portion of the internal jugular vein in the tufted capuchin monkey (cebus apella) begins at the level of the terminal segment of the sigmoid sinus, extends by the wall of the initial portion of the mentioned vessel, which is in the posterior compartment of the jugular foramen, up to the inferior third of the first portion of the internal jugular vein. was observed in cebus apella, like in man, that the superior two third ... | 1983 | 6881535 |
| efficacy of amoscanate against experimental schistosomal infections in monkeys. | the antischistosomal activity of oral doses of amoscanate (4-isothiocyanato-4'-nitrodiphenylamine) was determined in infected cebus apella (capuchin monkeys) and macaca mulatta (rhesus monkeys). in c. apella infected with schistosoma japonicum or s. mansoni an initial dose of 10 mg/kg body weight did not alter fecal egg counts, but a subsequent dose of 25 mg/kg markedly reduced both egg counts and worm burdens; in animals infected with s. haematobium, a single dose of 25 mg/kg of amoscanate was ... | 1983 | 6625061 |
| sensorimotor unit activity related to intention in the pulvinar of behaving cebus apella monkeys. | previous observations made in our laboratory in a waking behaving cebus apella monkey revealed that neurons of the pulvinar nucleus of the thalamus discharged preferentially in relation to intentional movements of the limbs and eyes. we give here a description of further observations made in two waking, behaving cebus apella monkeys trained to perform two tasks: in the first to make saccadic eye movements to eccentrically placed visual targets; in the second, to make projection movements of the ... | 1983 | 6653702 |
| antidyskinetic action of 3-ppp, a selective dopaminergic autoreceptor agonist, in cebus monkeys with persistent neuroleptic-induced dyskinesias. | four cebus apella monkeys with persistent dyskinetic movements induced by earlier long-term administration of haloperidol were subjected to a trial of the dyskinesia-modifying effects of a novel dopamine autoreceptor agonist 3-ppp (3[3-hydroxyphenyl]-n-n-propyl-piperidine). three monkeys had choreic dyskinesia involving trunk and extremities whereas one had a buccolingual form including tongue protrusion with choreoathetotic twitching and twisting movements of the tongue. two monkeys (1 choreic, ... | 1983 | 6663299 |
| the meiotic chromosomes of cebus apella (cebidae, platyrrhini). | an analysis of the meiotic chromosomes of cebus apella (cebidae, platyrrhini) has allowed for the visualization of constitutive heterochromatic regions throughout the meiotic cycle and has permitted the identification of four chromosomes in the first and the second divisions. in pachytene nuclei, and in pachytene spreads where synaptonemal complexes were visible, one heterochromatic region was frequently unpaired. no chiasmata were found in heterochromatic regions, and there was no evidence of c ... | 1983 | 6685608 |

| fluphenazine-induced acute and tardive dyskinesias in monkeys. | five cebus apella monkeys were treated with biweekly injections of fluphenazine enanthate (0.1-3.2 mg/kg im). three of these completed 1 full year of treatment, one injured its leg after 6 months of treatment and was killed, and another died of unknown causes after 9 months of treatment. all monkeys displayed abnormal movements corresponding to the early appearing extrapyramidal symptoms of neuroleptic-treated patients. these consisted initially of slowing or absence of volitional movement, trem ... | 1984 | 6440175 |
| cortical projections to the paramedian tegmental and basilar pons in the monkey. | the efferent connections of the cerebral cortex to paramedial tegmental and basilar pons were studied in the monkey by using the retrograde and orthograde capabilities of the horseradish peroxidase (hrp) technique. six capuchin monkeys (cebus apella) received transcannular pontine hrp gel implants to retrogradely label the cells of origin of corticopontine projections. four additional capuchin monkeys, one rhesus (macaca mulatta), and one cynomolgus (macaca fascicularis) monkey, received hrp gel ... | 1984 | 6480918 |
| [comparative anatomical studies of the vomeronasal complex and the rostral palate of various mammals. i]. | the anatomy of the vomeronasal complex and, in connection with this, the structures of the rostral palate were studied in different species of mammals, namely members of the order marsupialia, scandentia, insectivora, primates, rodentia, and lagomorpha. the following results were obtained: the organs of jacobson of all forms studied are well-developed. the organ of jacobson is situated at the base of the nasal septum and opens rostrally, always closely connected to the nasopalatine duct. even in ... | 1984 | 6489726 |
| comparative responses of vaginal mucosa to chronic pyrimidinone-induced irritation. | intravaginal studies in guinea pigs, cebus monkeys (cebus apella), and beagles were made with an anti-herpes drug, 2-amino-5-bromo-6-phenyl- 4(3h)-pyrimidinone (abpp). concentrations of 5 to 40 mg/ml, suspended in saline or polyethylene glycol, were given for periods of 2 1/2 to 90 days. very little gross evidence of injury was observed. histologically, the regimens brought about increasing degrees of mononuclear cell infiltrations (histiocytes, lymphocytes, and plasma cells) in the vaginal lami ... | 1984 | 6515276 |
| species- and stage-specific antigens in exoerythrocytic stages of plasmodium falciparum. | numerous exoerythrocytic forms of plasmodium falciparum ( pfeef ) were obtained from the liver of the south american monkey, cebus apella, for analysis of the antigens on this stage. as antigen for the fluorescent assay, 5-micron sections of liver fragments collected on day 5 following sporozoite inoculation and fixed in carnoy's solution or kept in liquid nitrogen were used. two types of fluorescent labeling of the pfeef were identified: diffuse and peripheral. each of 23 sera from individuals ... | 1984 | 6203418 |
| effects of sulpiride on persistent neuroleptic-induced dyskinesia in monkeys. | five cebus apella monkeys with persistent neuroleptic-induced dyskinesia were given a single dose of sulpiride (20 mg/kg i.m.). the dyskinesia was reduced in all five although four developed attacks of acute dystonia which had to be reversed by anticholinergic medication in three animals. in one monkey the administration of classic neuroleptics had earlier been shown to induce a typical sequence of events. first there was a similar reduction of dyskinesia as seen in the other monkeys, 1-2 days l ... | 1984 | 6142586 |
| discrete regional distribution of biochemical markers for the dopamine, noradrenaline, serotonin, gaba and acetylcholine systems in the monkey brain (cebus apella). effects of stress. | brains from cebus apella monkeys have been mapped biochemically using a cryo-section technique which enables exact micro-dissectioning of tissue. two neurotransmitters; noradrenaline (na) and gamma-amino-butyric acid (gaba) were measured by gas chromatography-masspectrometry technique. in addition biochemical markers reflecting metabolic activity in the dopamine (homovanillic acid, hva, 3, 4-dihydroxyphenylacetic acid, dopac), serotonin (5-hydroxyindoleacetic acid, 5-hiaa), noradrenaline (4-hydr ... | 1984 | 6150601 |
